RE GULATING DEVICE,FOR GAS-GENERATORS.

SPECIFICATION forming part of Letters Patent N0. 795,091, dated July 18, 1905.

Application filed December 13, 1904:. Serial No. 236,710.

To a, 1077/0711. 1% IN/W] concern:

Be-it known that LQUIMBY S. BAoKUs, a citi- Zen of the United States, residing at Brandon, in the county of Rutland and State of Vermont, have invented certain new and useful Improvements in Regulating Devices for Gas- Generators; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My present invention relates to the art of manufacturing oil-gas; and it has for its object the production of a producing apparatus which shall be cheap and simple in construction and eflicient and automatic in operation and which shall be capable of being constructed in sizes suitable to the conditions under which it is to be operated, so that it can be used to supply heat andlight to asingle dwelling or for such larger building or buildings as may be desired. The construction of such a device to successfully meet the requirements of actual use must be also safe and capable of being operated by persons having little or no knowledge of mechanics or of the art to which the said device belongs and should not require constant attention.

To this end I have constructed agas generating and regulating device, which is clearly illustrated in the drawings and disclosed in the following description and claim.

In the drawings, Figure 1 is a View, partly in elevation and partly in section, of a machine embodying my invention. Fig. 2 is a longitudinal section of the regulating-valve, and Fig. 3 is a like view of the cut-off valve.

In the figures, A is the generator, which is supplied with oil brought from any suitable source of supply, such as the gasolene or oil holder A, by a pipe a. This pipe connects with a coil (0 forming the retort. This retort is connected by pipe b with the pipe B, leading to the regulator C, which is constructed like the ordinary gas-holders. Thisregulator may be madeof a sufficient size to act as a gas holder or receptacle for the storage of gas, or it may be made quite small and act only as a regulator, the gas after passing through the same being conducted to a holder through a check-valve b a suflicient amount of air to give a resultant gas of the desired richness. The check-valve 7f admits air to the pipe B, but prevents any outflow from the pipe at that point.

The valve-stem of the valve 6' is provided with an arm 0, and the outer end of such arm has a jointed connection with an upwardlyextending red C. This rod extends through an opening in the arm 0, rigidly connected to the bell of the regulator C, and is provided above and below such arm with the adjustable stops 0 and 0 which are placed at such points that when thebell of the regulator descends to near its lowest position it will engage the stop 0 and depress the rod C, causing it to turn the cut-off valve and open the same to give free communication between the retort a and the regulator, and when the bell of the regulator rises to near its highest position the arm 0 will engage the stop 0 and lift the rod 0, causing it to turn the cut-oif valve 6 in a direction to cut off the passage of gas from the retort to the regulator C. By preference the stop 0 is so placed that when the bell of the regulator is at its highest point the cut-off Valve will be turned not quite far enough to entirely shut off the passage of all gas from the retort to the regulator, but will permit the passage of a small amount of gas to the regulator, preferably about enough to supply the burner beneath the retort.

D is a pipe extending from the interior of the regulator and connecting withthe pipe D. To the upper end of this pipe the pipe (Z is connected, leading to the burner E below the retort a The connection between the pipe I) and the pipe at is made through the injector-valve or jet-mixer 0. The pipe (Z is provided with openings. for the admis sion of air to reduce the gas passing through the injector-valve to such an admixture as will secure complete combustion and is provided with a sleeve 6Z2, movably mounted on the pipe d and having openings of the same size as those of the pipe d and when desired registering therewith. This sleeve can be turned to partially close the-openings in the pipe CZ to assist in regulating the quality of the gas supplied to the burner. The pipe D is also provided with the cooks d and (Z and a pipe D is connected therewith leading to a storage receptacle or holder or to the place or places at which the gas is to be utilized. By closing the cock d gas can be cut off from the burner. At the same time by leaving the cock d" open gas will continue to pass from the regulator through the pipe I). By closing the valve 6Z3 all egress of gas from the regulator can be prevented.

The pipe a is provided with the cock a by which the flow of oil or gasolene to the retort may be cut off when this is desired.

The oil-supply tank or holder A will preferably be placed at a distance from the other parts of the apparatus and may be so placed that the oil will flow by gravity, or it may be provided with means whereby oil may be caused to flow to the retort by air-pressure. The pipe D is preferably provided with the drip-cock a by which any accumulation of liquid in the pipe D may be drawn off.

0 is a cock for drawing off the water from the generator when this maybe desired.

' The cut-off valve or cock 6 is shown in section in Fig. 3, in which it will be seen that the valve F is secured in the valve-casing by the packing f, the loose ring f, and the cap f. This construction secures the valve in place and prevents leakage and at the same time enables the valve to be adjusted to take up wear. The needle valve 6 is secured against leakage by packing in like manner.

The casing of the retort or generator is provided with a lining of asbestos g, which prevents the waste of heat by radiation, whereby a desirable degree of economy is attained.

The operation of the device will be apparent from the foregoing description. It is to be noted that the quality of the gas passing to the regulator is regulated entirely by the operator through the needle-valve b andwhen this quality has been fixed by the setting of this valve so long as the machine is in operation the gas will be of the same quality no matter whether it is furnished in large or small quantities. The regulation by the regulator C does not in any substantial degree affect the quality of the gas produced. It will also be noted that the machine can be started and that it will continue in operation with varying demands upon it without more than casual attention.

What I claim, and desire to secure by Letters Patent, is-

The combination with the generator and an oil-supply therefor, of the regulator, a pipe leading from the said generator to the regulator, said pipe being provided with ajetmixer,a needle-valve for regulating the size of the jetorifice, a cut-off valve between the said needle-valve and the generator, and connections between the regulator and said cut-ofl" valve whereby the presence of a certain amount of gas in the regulator will reduce the flow of gas to the regulator and an undue reduction of the amount of gas in the regulator will increase the flow of gas to the regulator without affecting the relative proportions of air and gas in the mixture, substantially as described.

In testimony whereof I affix my signature in the presence of two witnesses. V
